Large-aperture & high-resolution optically addressed spatial light modulator

The project was aimed to the development, prototype making and bringing to the stage of serial production of original optically addressed spatial light modulator (OASLM). New method of photosensitive element manufacturing for OASLM with monocrystal Bi12SiO20 (BSO)  or Bi12GeO20 (BGO) had been proposed on the basis of Patent N 57025, Russia. The use of thin BSO crystal plates as a photosensitivity elements of such type modulators allows one to achieve better optical resolution at keeping of the other optical parameters. The use of assembled photoconductive element on single substrate allows one to produce similar type modulators with larger aperture and better resolution. The innovation of photoconductive element making creates original kind of product for laser system market. The project had been supported for 2 years period. The project was directed to the investment bringing in company manufacture facilities development.

Optical high current sensors and devices

Operation principle of optical high current sensors (OCS) is based on Faraday magnetooptical effect for measurement of a magnetic field and, accordingly a current into conductor. Faraday magneto-optical effect consists in linear change of polarization of light which is passing through crystal Bi12GeO20 (BGO) under the influence of a magnetic field, that similarly allows to spend the measurements of the current into conductor.

Optical high voltage sensors

Optical voltage sensors (OVS) based on electric field intensity measurements by Pockels electro-optic effect in crystal Bi12SiO20 (BSO). Main advantage of OVS with BSO crystal is thermostable sensor operating for optimal BSO crystal length in dependence on usable light  wavelength (Patent N 83340, Russia) into crystal.  The aim of the project is to create novel thermostable voltage and electric-field sensors for different fiber wavelength.
